nifind - find a directory in the NetInfo hierarchy SYNOPSIS
nifind [ -anvp ] [ -t timeout ] directory [ domain ] DESCRIPTION
nifind searches for the named directory in the NetInfo hierarchy. It starts at the local domain and climbs up through the hierarchy until it reaches the root domain. Any occurrences of directory are reported by directory ID number. If the optional domain argument is given, then nifind stops climbing at that point in the hierarchy. The domain argument must be specified by an absolute or relative domain name. When invoked with the -a option, nifind searches for the named directory in the entire NetInfo hierarchy (or the subtree with domain as the root if domain is specified). The -n option exempts local domains from the search. nifind uses a default two second connection timeout when contacting a domain. The connection timeout can be overridden with the -t option. OPTIONS
-a Search for directory in the entire NetInfo hierarchy. -n Exempt local directories from the search. -p Print directory contents. -t timeout Specify an integer value as the connection timeout (in seconds). -v Produce verbose output. EXAMPLES
% nifind /printers/inky /printers/inky found in /software, id = 202 /printers/inky found in /, id = 357 % nifind -a /machines/mailhost /sales /machines/mailhost found in /sales, id = 234 % nifind -v /users/uid=164 /users/uid=164 not found in /sales/polaris /users/uid=164 not found in /sales /users/uid=164 found in /, id = 451 % nifind -p /machines/mailhost /machines/mailhost found in /sales, id=171 name: zippy mailhost ip_address: 192.42.172.5 /machines/mailhost found in /, id = 350 name: zorba mailhost ip_address: 192.42.172.1 SEE ALSO

squid_ldap_auth(8) System Manager's Manual squid_ldap_auth(8) NAME
squid_ldap_auth - Squid LDAP authentication helper SYNOPSIS
squid_ldap_auth -b "base DN" [-u attribute] [options] [ldap_server_name[:port]]...] squid_ldap_auth -b "base DN" -f "LDAP search filter" [options] [ldap_server_name[:port]...] DESCRIPTION
This helper allows Squid to connect to a LDAP directory to validate the user name and password of Basic HTTP authentication. The program has two major modes of operation. In the default mode of operation the users DN is constructed using the base DN and user attribute. In the other mode of operation a search filter is used to locate valid user DN's below the base DN. -b basedn (REQUIRED) Specifies the base DN under which the users are located. -f filter LDAP search filter to locate the user DN. Required if the users are in a hierarchy below the base DN, or if the login name is not what builds the user specific part of the users DN. The search filter can contain up to 15 occurrences of %s which will be replaced by the username, as in "uid=%s" for RFC2037 directo- ries. For a detailed description of LDAP search filter syntax see RFC2254. -u userattr Specifies the name of the DN attribute that contains the username/login. Combined with the base DN to construct the users DN when no search filter is specified (-f option). Defaults to 'uid' Note: This can only be done if all your users are located directly under the same position in the LDAP tree and the login name is used for naming each user object. If your LDAP tree does not match these criterias or if you want to filter who are valid users then you need to use a search filter to search for your users DN (-f option). -s base|one|sub search scope when performing user DN searches specified by the -f option. Defaults to 'sub'. base object only, one level below the base object or subtree below the base object -D binddn -w password The DN and password to bind as while performing searches. Required by the -f flag if the directory does not allow anonymous searches. As the password needs to be printed in plain text in your Squid configuration it is strongly recommended to use a account with mini- mal associated privileges. This to limit the damage in case someone could get hold of a copy of your Squid configuration file. -P Use a persistent LDAP connection. Normally the LDAP connection is only open while validating a username to preserve resources at the LDAP server. This option causes the LDAP connection to be kept open, allowing it to be reused for further user validations. Recom- mended for larger installations. -R do not follow referrals -a never|always|search|find when to dereference aliases. Defaults to 'never' never dereference aliases (default), always dereference aliases, only while searching or only to find the base object -h ldapserver Specify the LDAP server to connect to -p ldapport Specify an alternate TCP port where the ldap server is listening if other than the default LDAP port 389. EXAMPLES
For directories using the RFC2307 layout with a single domain, all you need to specify is usually the base DN under where your users are located and the server name: squid_ldap_auth -b ou=people,dc=your,dc=domain ldapserver If you have sub-domains then you need to use a search filter approach to locate your user DNs as these can no longer be constructed direcly from the base DN and login name alone: squid_ldap_auth -b dc=your,dc=domain -f uid=%s ldapserver And similarily if you only want to allow access to users having a specific attribute squid_ldap_auth -b dc=your,dc=domain -f (&(uid=%s)(specialattribute=value)) ldapserver Or if the user attribute of the user DN is "cn" instead of "uid" and you do not want to have to search for the users then you could use something like the following example for Active Directory: squid_ldap_auth -u cn -b cn=Users,dc=your,dc=domain ldapserver If you want to search for the user DN and your directory does not allow anonymous searches then you must also use the -D and -w flags to specify a user DN and password to log in as to perform the searches, as in the following complex Active Directory example squid_ldap_auth -p -R -b dc=your,dc=domain -D cn=squid,cn=users,dc=your,dc=domain -w secretsquidpassword -f (&(userPrincipal- Name=%s)(objectClass=Person)) activedirectoryserver NOTES
When constructing search filters it is strongly recommended to test the filter using ldapsearch before you attempt to use squid_ldap_auth. This to verify that the filter matches what you expect. AUTHOR

Will crash if other % values than %s is used in -f, or if more than 15 %s is used. QUESTIONS
